Andrea Gross, the mother of Adam Goldstein, has amended her son's $20 million lawsuit against the manufacturer of the Learjet that crashed upon takeoff in September 2008 with Goldstein and Travis Barker onboard. Also named in the lawsuit are the estates of the deceased pilots and others. According to a People report, Los Angeles court papers show that Gross has added a wrongful-death claim to her son's lawsuit.

"The crash ultimately caused Adam Goldstein's death at a later date," the document reads.

A trial is set for March 2, with Learjet continuing to deny responsibility for the crash.

DJ AM and Blink-182 drummer Barker were flying out of Columbia, South Carolina, in the early morning of September 19, 2008, following an event with Perry Farrell and Gavin DeGraw. After sparks emanated from the plane, it crashed through a fence and caught fire, killing the pilots and four others. DJ AM and Barker miraculously escaped, although they were badly burned.

After seemingly making a full recovery, DJ AM was found dead almost a year later to the day in his New York City apartment. Later that month, the New York medical examiner determined that Goldstein's death was an accidental overdose caused by a variety of legal and illegal drugs in his system.

It is presumed that Gross will cite the 2008 plane crash as leaving DJ AM in so much pain that he sought relief through the various drugs. In the months since his death, several of DJ AM's friends and supporters have similarly blamed his death on the trauma he suffered from the crash.
